CHINO HILLS - A group of residents concerned about an alleged Chinese maternity hotel operation in the city will hold a community meeting Thursday night.

The Not in Chino Hills grassroots group will host the meeting at 6:30 p.m. at the Grand Avenue Park community center, 1301 Grand Ave.

Chino Hills officials and residents said a house at 15250 Woodglen Drive is being used for wealthy Chinese women to give birth.

After obtaining a court-ordered inspection warrant two weeks ago, city officials said they expect to soon file a criminal complaint against homeowner Hai Yong Wu because of a number of code enforcement violations.

"We're trying to connect with people to see what they've found out," said Linda Spencer, who resides near the alleged maternity hotel.

"I think people are starting to question if it's happening in their neighborhood. We want people to voice their opinions on that and figure out what our next steps are."

The mission of Not in Chino Hills is to preserve their family oriented community.

"We want to continue to enjoy our beautiful city and we welcome every. But to preserve what we cherish we must also protect our city," the group's website says.

"Our mission is to keep a vigilant eye and use our efforts necessary to do so. We are a grassroots organization who will organize and rally behind a cause that will serve the families of Chino Hills."

Residents said the goal of the meeting is to provide information on crucial issues that impact families.

"Presently, we are facing the `maternity hotel' issue, which we plan to deal with head on," according to the website.

On Wednesday, city officials said the criminal complaint against Wu has yet to be filed.

Wu allegedly violated ordinances against operating what the city considers a hotel in a residential house and against altering the structure of the house without permits, City Attorney Mark Hensley said.

The complaint will detail the allegations against Wu and, when filed in court, will formally begin the criminal process.

"My biggest concern is they're operating a business out of a residential area. And they're doing it blatantly," said Ron Watts, who also lives down the street from the home in question.

"The other concern is the anchor babies, but that's a federal issue."

Watts, who has lived in the neighborhood for 26 years, described the two-story house as having a 1920s Spanish hacienda-style and a courtyard.

The house, which many call a mansion, is just southwest of Chino Hills Parkway and Peyton Drive.

Watts said since the house is likely not listed as a business it is also not paying taxes.

"They obviously knew what they were doing," he said. "And now the city is going through all these steps with taxpayers money. I think the city will resolve it, but in due time."
